Xcode Command Line Tools

Apple’s starter toolkit. Install this before Homebrew.

First install: Xcode Command Line Tools, a small bundle of build utilities from Apple. Lots of developer software quietly depends on it, including Homebrew, which you'll install next. You don't need the giant full Xcode app; this slim version is plenty.

1. 1

   Open your terminal and paste this in:

   TerminalCopy

   xcode-select --install

2. 2

   Press Enter. A system dialog usually pops up offering to install the tools. Click Install, accept the license, and let it run. A few minutes on most connections.

3. 3

   Already have them? Then instead of a dialog you'll get an error like the one below. That's not a problem: it literally means “you're done, move on.”

   TerminalCopy

   xcode-select: error: command line tools are already installed, use "Software Update" in System Settings to install updates

Done. Next: Homebrew, which handles every install after this one.
